, 9 Claims.

The present application relates to variable speed drive controls forspinning frames, and the like; and the primary object of the inventionis to improve controls of that general character in minor details.Particularly, the present invention has for its primary object torearrange the elements of control mechanisms of the above generalcharacter for the purpose of reducing the floor space required toaccommodate such a control. A

further object of the invention is'to simplify the various driving andwhereby the efliciency of the organization as a whole is somewhatimproved. Further objects w of the invention will appear as thedescription proceeds.

To the accomplishment of the above and related objects, my, inventionmay be embodied in the form illustrated in the accompanying drawings,attention being called to the fact, however,

that the drawings are illustrative only, and that change may be made inthe specific construction illustrated and described, so long as thescope of the appended claims is not violated.

Fig.1 is a perspective view of one end of a conventional spinning frame,with which is operatively associated my improved drive and control;

Fig.2 is a fragmental view, showing the drive connections between thespinning frame and the control;

Fig. 3 is an end elevation, upon an enlarged scale, of parts of theorganization, certain parts being broken away for clarity ofillustration;

Fig. 4 is a fragmentary end view of the organization illustrated in Fig.3;

Fig. 5 is a fragmentary sectional plan of certain elements of thecontrol;

Fig. 6 is a plan view of the control per se, parts being broken away forclarity of illustration; and Fig. '7 is a transverse section takensubstantially on the line 1--1 of Fig. 6, and looking in the directionof the arrows.

Referring more particularly to the drawings,

' it will be seen that I have illustrated a portion of a conventionalspinning frame. It, including the usual ring rail ll driven,'as usual,from the oscillating shaft l2. As is clearly shown in Fig. 2, said shaftl2 carries an arm 13 which is connected, by a link I4, with an arm 15which, as will appear from the following description, operates, uponoscillation, to drive the elements of the control to vary'the speed atwhich the spinning frame is driven.

The entire control, of the present application is assembled upon a tableIt which is securedtothe end frame, ll of the driven machine, and

which is further supported by legs l8. A standard l9 supported upon thetable provides a support and bearing for one end of the input shaft 20of a variable speed transmission. The other end of said shaft issuitably supported and jour- 5 naled in a bearing (not shown). Asecondstandard 2| provides a bearing for one end of the output shaft 22 of thetransmission. Said shaft 22 may be themain shaft of the spinning frameH), or it may be connected, in a suitable manner, to The transmission ispreferably housed in a housing 23 of suitable characteristics.

Splined upon the shaft 20 is a coned,disc 24; and a second coned disc 25is fixedly mounted on 15 said shaft 20 in facing relation to the disc24, as is clearly shown in Fig. 4. It will be obvious that, as the disc24 is shiftable axially of the shaft 20, said discs 24 and 25 cooperateto form anex- Fixed on the shaft 22 is a 20 coned disc 26which'cooperates with a similar coned disc (not shown) splined on theshaft 22 and resiliently urged, toward the disc 26, to form aresiliently expansible V-pulley. An edge-active V-belt 21 provides adriving connection between 25 the pulley formed by the discs 24 and 25and the pulley formed by the disc 26 and its mate; whereby the shaft 22is driven from the shaft 20, and whereby the speed of the shaft 22 maybe varied by axial shifting of the disc 24 along the shaft 20. 0

If desired, either or both of the shiftable discs may be splined upon aprojected hub of its associated fixed disc.

Suitably mounted upon the housing 23 is a shaft 28 which provides apivotal mounting for a 3d motor platform 29 which is formed withslideways 30. A motor 3| is adjustably mounted in the slideways 3D; andthe platform may be adjusted, about the axis of the shaft 28, to movethe motor 3| toward or away from the shaft 20, by means of the screw 32.A suitable sheave 33 is carried on the motor spindle 34; and a suitablesheave 35 is carried on the shaft 20, whereby the'motor 3i drives theshaft 20 through a connecting belt, as shown.

A yoke 36 is connected, through a suitable thrust bearing means whichforms no part of the present invention, to the disc 24; whereby saiddisc 24 may be positively shifted in either direcr tion axially of theshaft 20 by corresponding movement of the yoke 36. Pivotally connectedto the yoke 36 at diametrically opposite points 31 are two straps 38which, at the points 39, are

' pivotally connected intermediate their ends with links 40, pivoted at4| on the standard 9. The

lower ends of the straps 38 are bifurcated, as is clearly shown in Fig.4, to straddle the op posite ends ries a beveled gar 52 meshing with asecond beveled gear 53 carried on a shaft 54 which like wise projectsinto the box 5|.

Secured to, and carried by, -the table I6 is a casing indicatedgenerally at 55 and comprising a bottom 56, upwardly projecting sidewalls 51 and 58, and upwardly projecting end walls 59 and 60. The endwall 60 is cut away, as: at GI, and thereis provided a closure 62suitably secured in place to cover the the wall 60.

As is clearly to be seen in 'Figs. 3 7 arm l5 merges into a hub 63 whichis loosely mounted on the shaft 54, and which is provided spring 1| withthe arm 69 of the pawl 68; and said ratchet face with crown the pressureplate 8|; 7

The operation from the above of the organization will be cleardescription, but may be briefly is energized, it

viewed in Fig. 7. '\Both of the clutch discs .15 and being. engaged withwheels 16 and 11, such movement of the ratchet wheel 11 will betransmitted through the clutch element 18 to the shaft 54. So long asthese conditions remain constant, the ratchet wheel 76 will likewise bedriven in a clockwise direction, through the clutch element 12.

Clockwise rotation therespective ratchet strike the latch I08, Iintoengagement with the ratchet wheel 16;

, actuated by rotation tion to disengage said first clutch means, meansoscillation of said arm to toward the right, as viewed in Fig. 6, willcause the element 96 to force the clutch element 18 toward the right, asviewed in Fig. 6, against the pressure of the spring 82, to disengagethe clutch disc 80 from the ratchet 11.

At some time thereafter, the finger I09 will to throw the pawl armwhereafter, oscillation of the element 61 will resultin counterclockwiserotation of the ratchet wheel. 16. That rotation will be transmitted,through the clutch element 12, to the shaft 54; whereby the nut 9| willbe moved gradually toward the left, thus permitting the clutch disc 80again to engage the ratchet wheel 11. Such rotation will also causeclockwise rotation of the shaft 44, as viewed in Fig. 3, to move the nut43 upwardly, as viewed in Fig. 5; thereby moving the disc 24 away fromthe disc 25 to reduce the speed of the shaft 22. After a predeterminedperiod of operation, the ends'92 and 93 of the nut 91 will engage andmove the stop collars 86 and 89 to disengage the clutch disc from theratchet wheel 16.
